ART OF MAKING CLUSTER-SETTINGS.

Specification of Letters Patent.

Application filed February 19, 1910.

Patented July 19, 1910. Serial No. 544,843.

To all whom it may concern:

Be it known that I, JAMEs A. DORAN, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a certain new and useful Improvement in the Art ofMaking Cluster-Settings, of which the following is a full, clear, andexact description.

The object of this invention is to produce economically a clustersetting for jewels, such as stones, gems, or other ornaments, which maybe given a variety of shapes, and will retain the jewels firmly inplace, with out the use of solder for connecting the several settingsconstituting the cluster.

The invention consists in the improvement in the art of forming jewelsettings from sheet metal by a series of cupping or drawing and cuttingoperations, whereby a series of closely connected individual settings,cups, hearings or seats, with integral prongs, is produced, capable, asa whole, of being given a variety of shapes, to produce pinheads,hat-ornaments, and a great variety of articles, both utilitarian andornamental, all as I will proceed now more particularly to set forth andfinally claim.

In the accompanying drawings, illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure l is a planview of part of a cupped sheet of metal, and Fig. 2 is a par tialsection and edge view thereof. Fig. 3 is a top plan view of a similarsheet having the cupped portions provided with cross cuts, to form theclaws or prongs for retaining the jewels, and Fig. 4 is a partialsection and edge view thereof. Fig. 5 is a top plan view of the sheet ofFigs. 3 and 4 after being drawn to produce the cups, bearings, or setsfor the jewels, and the claws or pron 's, and Fig. 6 is a partialcross-section and edge view thereof. Fig. 7 is a bottom plan view, andFig. 8 is a top plan view, on a larger scale, of a single settingcomplete and parts of eight adjacent settings, all connected inaccordance with this invention. Fig. 9 is a view similar to Fig. 6 butshowing settings having solid instead of perforated bottoms. Fig. 10 isan elevation of a cluster setting for a hat pin.

A sheet, 1, of suitable metal stock is drawn to provide a series ofcone-like projections 2, and these are provided with the crosscuts 3which divide each projection into four equal sections 4. At uniformintervals between these cross-cuts projections, the sheet of metal isprovided with holes 5, and with these holes as centers, the metal isdrawn in a direction opposite to the projections 2 and so as to formcups 6 of sub stantially circular cross-section and of the form of atruncatedcone, to receive the jewels, with the sections 4 standing upfrom their upper edges to form the claws or prongs for holding thejewels in place in the cups. Each cup so drawn is connected with itsfour adjacent similar cups by means of strips 7 integral with them andwith the sheet from which all are produced, as more clearly shown in theenlarged views Figs. 7 and 8. In thus drawing these cups the holes 5 arenecessarily stretched, but without detriment to the setting. As shown inFig. 9, the cups may be drawn without forming the holes 5, and in suchcase the bottoms of the cups will be solid.

As an illustration of one use of my invention, I have shown a hat-pinhaving a flat, angular setting; but, as already stated, the setting maybe variously shaped, and used for a variety of purposes.

By the invention, a cluster setting of any number of self-connected,individual jewel settings (cups, seats, or bearings), may beeconomically produced, and without the use of solder or otherextraneously applied connections.

In accordance with former practice in making cluster settings, the workdepended upon the correctness of the workmans eye and the steadiness ofhis hand to secure regular or uniform spacing, whereas by my inventionabsolute regularity and uniformity are secured, and the symmetry of theproduct assured. Furthermore, where individual settings are used, itoften happens that some of them are not thoroughly soldered, andconsequently soon fall oii' either in handling or in use.

Efforts have been made to produce cluster settings in one piece, but.the practice followed in such instances has resulted in such a widespacing apart of the individual settings as to preclude obtaining thedesired cluster effects.

In following the present invention, it is possible to make sheets ofsettings connected as described, and then cut up the sheets into suchportions as may be necessary to form the desired cluster setting, andthese cluster settings may be bent to form various shapes,

such as hemispherical, conical, cylindrical, saucer-shape, etc.

From the foregoing, it will be understood that the raw product of thisinvention is practically, jewelers stock, in which the cups 6 constitutebearings or seats for any suitable ornaments, such as stones, gems, orother articles 8, Fig. 10, all which I intend to embrace by the use ofthe term jewel.

It will be understood that in using the stock, the half settings shownat the ends in Figs. (3 and 9 would be cut off.

lVhat I claim is 1. The improvement in the art of making clustersettings from sheet metal, which consists in forming a series ofcontiguous upright projections in the metal with intervening solidportions, then separating the metal of the projections to form theprongs, and then cupping these solid portions in the reverse directionto the projections and developing the intervening connections of theseveral settings.

2. The improvement in the art of making cluster settings, which consistsin drawing up conical projections in a sheet of metal, cross cuttingsaid projections so as to leave solid connections between them, and thencupping the metal between the projections to form the jewel cups, anddrawing up the proximate cross-cut sections of four adjacent projectionsto form the prongs, said solid connections tying the individual jewelcups in series.

3. The improvement in the art of making cluster settings, which consistsin drawing up conical projections in a sheet of metal, cross cuttingsaid projections so as to leave solid connections between adjacentsurrounding projections, and then cupping the metal between theprojections to form the jewel cups, and drawing up the proximatecrosscut sections of four adjacent projections to form the prongs.

4. The improvement in the art of making cluster settings, which consistsin drawing up conical projections in a sheet of metal, cross cuttingsaid projections so as to leave solid connections between the adjacentsurrounding projections, perforating the sheet of metal at regularintervals between the conical projections, drawing frusto-conical cupsin said sheet with said perforations as centers, and throwing up themetal between the cross cuts to form prongs on the edges of the cupportions.

In testimony whereof I have hereunto set my hand this 17th day ofFebruary A. D. 1910.

It is hereby certified that in Letters Patent No. 964,624, granted July19, 1910, upon the application of James A. Doran, of Providence, RhodeIsland, for an improvement in the Art of Making Cluster-Settings, errorsappear in the printed specification requiring correction, as follows:Page 1, line 12, the Word sets should read seats, and same page, line58, the compound word cross-cuts should read crosscut; and that the saidLetters Patent should be read with these corrections therein that thesame may conform to the record of the case in the Patent Olfice.
